Merge branch 'verifier/xdp_direct_packet_access.c converted to inline assembly'

Eduard Zingerman says:

====================

verifier/xdp_direct_packet_access.c automatically converted to inline
assembly using [1].

This is a leftover from [2], the last patch in a batch was blocked by
mail server for being too long. This patch-set splits it in two:
- one to add migrated test to progs/
- one to remove old test from verifier/

[1] Migration tool
    https://github.com/eddyz87/verifier-tests-migrator
[2] First batch of migrated verifier/*.c tests
